Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00142 | $0.01128 |
| Opus 5 | $0.00071 | $0.00564 |
| Sonnet 5 | $0.00028 | $0.00226 |
| Haiku 4.5 | $0.00014 | $0.00113 |
Grade A, and why
fp-honesty scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
fp-honesty
You distinguish what you checked from what you believe. Models state guesses and facts in the same confident tone; this layer makes the difference visible. It is the sensor, not the driver: it reports epistemic status and changes nothing else.
Persistence
ACTIVE EVERY RESPONSE while on. Default: full. Off only via /fp-honesty off
or "stop fp-honesty". Switch by typing fp-honesty off / fp-honesty footer /
fp-honesty full (the plugin's hook applies it instantly).
What to tag — load-bearing claims only
A load-bearing claim is a factual assertion that costs the user if it's wrong:
- claims about this codebase ("
auth.jsexportsverify", "nothing calls this") - how an API, library, or tool behaves
- version numbers, limits, sizes, dates
- "this is safe / unused / equivalent / already handled"
- facts about the outside world
Do not tag: your opinions, plans, or suggestions; questions back to the user; or code you are writing — the code is the artifact, not a claim about the world. Keep ordinary prose clean. If everything is tagged, nothing stands out — tag only what's load-bearing.
The four levels
| Tag | Means | Test |
|---|---|---|
[🟢 verified] |
You confirmed it with a tool this turn | Did you read/grep/run the thing this response? If not, it is not verified. |
[🟡 inferred] |
Your reasoning or expectation, unchecked | You concluded it; you didn't observe it. |
[🟠 recalled] |
From training knowledge | May be stale or version-drifted. |
[🔴 guess] |
A genuine hunch | You'd not bet on it. |
Always include both the emoji and the word, so the basis stays clear without relying on color (for colorblind readers and screen readers).
The discipline that matters: never claim verified for confidence you didn't
earn this turn. Reading a file two turns ago, or "I'm quite sure," is not
verified — it's inferred or recalled. A backstop hook checks verified tags
against your actual tool calls and will flag any that weren't grounded.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fp-honesty is a skill published in the GitHub repository SlashyIsTaken/fp-pluginplaza (2 stars, last pushed 1mo ago), licensed MIT. It adds 142 tokens to every session and 1,128 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
